So, instead of saying this isn't happening, why not look into how it could be done? They're doing it, I have no idea how. Take a look at new and you'll see that things are being controlled for the all, hot page.
I post almost every work day, I can see the patterns really well from my end. I don't care about upvotes as well, so I don't really have any emotion attached to it other than it pisses me off that I'm probably not seeing other things they don't want me to see. That's really what I hated about reddit too and why I came here.
They could have someone controlling it real time, yeah? That would explain the inconsistency of when I post out of the norm. I've been lightly testing them for years now, which is why I believe I can safely say these things.
